Intermediate 2
good luck for int2, higher & advanced higher
The big man of Physics has a special message for you:
I have classes periods 1 & 4 but you are free to stop by E3 any other time before the exam if you need some help.
Intermediate 2 Physics past papers and solutions
I have posted past papers and solutions on the Int2 Physics revision page. I don’t have copies of the very earliest papers, I’m afraid.

how satellites rule our world
BBC2 showed a really good programme about satellites last night. This screenshot showing a satellite passing over the Highlands is taken from about 17 minutes into the show. Click on the picture to visit the BBC’s own page about the documentary.
It was quite eye-opening to see just how much modern society relies on satellite technology.

good luck from Albert and me
I’m sure you’ll do your best tomorrow. Remember to check the exam advice for Higher and Standard Grade on BBC Bitesize.
Higher classes – remember my advice to attempt Section B first. 70 of the 90 marks are there and each mark requires less effort than Section A. Aim to leave 35 minutes for the multiple choice questions.
